Waiting,
You wrote that JWs teach that "creation happened with Adam & Eve 4000 BCE."
Actually they teach that Adam was created in 4026 BCE and that Eve was created sometime thereafter, possibly several or many years thereafter. In fact when the end did not come in 1975, 6000 years after their date for Adam's creation, they taught that their actual expected date for the end was 6000 years after Eve's creation. And since Eve was created after Adam, and possibly long after, the end may be yet to come 6000 years after that unknown date. If JWs are correct, Adam's been alone now in that garden for some 27 years now. I hope Eve wont keep him waiting much longer. : )
